- WIRE-DRAWING DRUM.

Specification of Letters Patent.

' l atented Sept. 25, 1906.

Application filed April 14, 1906. Serial No. 811,787.

To all whom it'may concern:

Be it known that 1, JAMES A. HORTON, of Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Wire-Drawposition sup ing Drums, of which thefollowing is a specification.

This invention relates to the drawing of wire composed of steel ormaterial of similar hardness; and its object is to enable the wire to besubjected to a large number of reductions in a single operationor-continuous process without breaking the wire or impairing its uniformquality.

The invention has particular reference to the construction of aWire-drawing drum having a wire-forwarding1 seat adapted to prevent theabrasion of t e wire running in contact with the drum, and thuspreventing the removal of the coating which is commonly a plied to thewire to prevent direct contact etween the material of the wire and thedrawing or reducing dies through which it is assed.

he invention consists in a wire-drawing drum having a wire-forwardingseat of a material which is softer than steel wire and means for claming and confining the relatively soft wire-fbrwardingfeat in such manneras to revent it from eing expanded or distorted y the combined action ofthe wire pressing against it and the lubricating comlied to thewire-forwarding seat, the dies during the drawing opthe wire, aneration.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a sectional view of the wire-drawing drum embodyingmy invention. Fig. 2 represents a section on line 2 2 of Fig. 1-.

The same numerals of reference indicate the same parts in both figures.

In the drawings, 10 re resents a wiredrawing drum, which ma e one of aseries of drums arranged in tan em order, as shown in Letters Patent ofthe United States No. 742,987, dated November 3, 1903, or the drum maybe one of a tier, as shown in Letters Patent No. 784,264, dated March 7,1905. In either case the drum may be mounted to rotate in a trough ortank adapted to hold a body of liquid lubricating composition in whichthe drum or drums are immersed, as shown in said Letters Patent No.784,264, or the lubricating composition may be-applied to the drum, thedies, and the wire by any other suitable means.

"12 represents awire-forwarding seat, the periphery of which constitutesthe surface of the drum with which'the wire is in contact. The said seatis made of a material which is, softer than iron or steel wire to theend that the coating of the wire will not be rubbed off nor the wlreabraded by frictioned contact with the drum. The material commonly usedfor coating all sizes of wire below the largest is bronze, composed ofcopper and tin, which is laced upon the wire in a suitable bath. 'l helarger sizes of wire are usually coated with a composition composed oflime or some analo ous material.

The wire-forwar in seat 12 of m present invention is compose of amateria which is softer than iron or steel wire. The said material maybe of any suitable non-abrasive character. For example, it may be any ofthe well-known forms of compressed aper or pa er-pulp, rawhide, or othersuitab e materia s, including hard wood. The said seat is of annularform and is closely confined or clamped between two metallic sections 13and 14 of the drum, the said sections being connected in such mannerthat they exert compressive ressure upon opposite sides of the seat 12,t e sections also projecting outwardlyl from the periphery of the seat12, so

that t ey prevent the spreadin or widening of the periphery of the seatby the pressure of the wire against it. The sections 13 and 14 arepreferably the edge portions of the peri hery of the seat and preventthe corners o the seat from wearing away and forming a crevice intowhich the wire might enter. Distortion of shouldered at 18 to overlapthe seat, due to the softening action of the 5 lubricating liquid and tothe pressure of the wire u on the seat, is thus prevented, and a drumavin a durable wire-forwarding seat free from lia ility to abrade thewire and remove the coating therefrom is rovided.

A wireforwarding seat of t is character permits the wire to be subjectedto alarge number of reductions in a single operation or continuousprocess without impairment of the wire or its coating and thereforewithout liability of breaking the wire or impairing its uniform quality.

If the seat 12 is made of Wood, a number of wooden sections 15 may beemployed, these being arranged with the grain of the wood extending in aradial direction from the center of the drum to its periphery andtightly clamped between the metallic sections 13 and 14. Any suitablehard wood, such as rockmaple, may be emplo ed The wood may be saturatedor treate with oil or paraflin to prevent the absorption of liquid.

I claim 1. A wire-drawing drum having a wireseat com osed of materialsofter than the wire, an means for confining said seat to preventspreading or distortion of the same.

2. A wire-drawing drum having a wireseat com osed of a material softerthan the wire,v an metallic drum-sections between which the said seat isclamped, the sections projecting outwardly from the periphery of theseat.

3. A wire-drawing drum havinga wireseat com osed of a material softerthan the wire, an metallic drum-sections between which the said seat isclamped, the sections projecting outwardly from the eriphery of theseat, and shouldered to over ap the edge portions of said periphe Intestimony whereo i I have aflixed my signature in presence of twowitnesses.
